The only reason for mastering technique is to make sure the body does not prevent the soul from expressing itself.
The best feeling in the world is feeling completely limitless when singing a song- no obstacle in your way, no note out of reach, no melody too tricky to master. The worst is feeling like you’re barely scraping by in the piece, unable to make choices regarding interpretation or style because you are limited by what your voice can physically produce.
Mastering vocal technique gives you options, it gives you choices. It expands the realm of what is possible. Working on technique does not mean you lose that original sound only you are blessed with- it expands what your God-given voice is capable of!
One other thought on the topic of choices: developing good technique is understanding what variables took you from point A to point Z. Good technique is the sum of so many small things- the shape of your vowels, the looseness of your jaw, the relaxation or engagement of certain muscles, the balance of air flow and vocal fold resistance. What allowed you to get the full, released sound on the word “Love” on a high F? Can you identify the small choices that got you there? Eventually, it becomes intuitive.
Work to technically improve your voice, like a ballerina or basketball player might improve their body and game. You’ll find a world of possibility open to you!
